See Storage Drive here: Most commonly used backup methodsĢ: Use a blank powered external drive (formatted GUID and OS X Extended Journaled in Disk Utility) and a copy of Carbon Copy Cloner to clone the OS X boot partition (aka Macintosh HD) to the external drive using the default settings and a full clone.ģ: Then reboot the machine holding the option/alt key down (wired or built in keyboard), you can now boot from the clone using Startup Manager. (reducing user content isn't mandatory below 50% filled but preferred if you want to see the best performance) Use Activity Monitor for this and reboot to see the changes if needed.

So my solution is if your serious about performance, have large files like video that stretch across many sectors and want it in one piece, want to reduce bad sectors that can corrupt large and even small files, need to free up space for a partition or large file.ġ: Reduce your boot drive user content (files, try movies first) so it's less than 50% of the drive filled (ideal) but never more than 80% filled as a full boot drive will make the computer not boot up.

If anyone has defragged a PC before knows it's never really completes in actuality, but this method I have here will do so wonderfully.

Unfortunately the only way to remedy this is by backing up users data off the drive to a external storage drive (not TimeMachine or clone) and then using Disk Utility to Erase with Zero (Security option or move slider one space to the right) the entire drive (10.6) or the Macintosh HD partition (10.7 or later) then reinstalling OS X fresh, followed by programs and return of verified user files.Įrase, formatting, OS X installs on Mac'sĨ: I don't advise using defragmentation software on a "live" system, it's dangerous and if it messes up your stuck. I always get twice as much boot hard drive space as I'm ever going to need, I can always partition the unused space and use it as a backup clone for on the road, or rare used items, emergency storage etc.ĥ: Over time (like years) a Mac can slow down as the adding and reduction of data, OS X upgrades and normal operation tends to move data making it less optimized.Ħ: If one wants to create a Bootcamp or second partition on the boot drive, there might be OS X data near the bottom where the second partition will go, it's sometimes not easy to move this data further up on the drive.īootCamp: "This disc can not be partitioned/impossible to move files."ħ: If there are bad or failing sectors on the drive, it can substantially slow down read speeds and the spinning beach ball effect occurs. So preferably if you can contain yourself to the first 50% of a hard drive, it will perform fast forever. Also things can get out of order, the heads have to travel further all over the drive to boot or load programs for instance.Ĥ: The first 50% of the drive is faster than the second 50% due to more sectors in each track which the heads have less to move and can gather more data at one time. However data doesn't magically move up to take available space, holes can develop with a lot of reads and writes. Data is first written on the top of the drive and works it's way down. SSD's no need.Ģ: You don't need to regularly defrag a Mac's hard drive, OS X writes small files in one batch, eliminating a lot of the need to defrag a Mac regularly.ģ: Hard drives are fastest at the beginning of the drive. If you have Filevault enabled this procedure will not work because it's one giant encrypted image, this is designed to acquire it's results by copying the parts of files into one piece again and back into a alphabetical order according to the root level directory for optimal results, especially of fast loading of Applications into memory.įirst if your experiencing computer problems, backup your personal information to a storage drive first, then consult the fix it options as defragging won't necessarily solve problems in software.ġ: Only hard drives require defragging. Also it stays optimized and faster longer when defragging software tends to require it again and again to regain the performance.

I outlined a safe way here that always gives you a bootable backup to check, plus it really optimizes the hard drive in the process. Perhaps once every few years after many updates, upgrades, program installs and reinstalls may one require it on a Mac, then rarely again. Well that's for Windows because the way it writes files it breaks them all up, OS X doesn't do that on small files, so it eliminates the need for MOST users to require a regular defrag.
You might be experiencing some performance issues with your Mac, spinning beach ball, just general slowness and you knew from your PC days about defragging computers.
